Ground subsidence is the gradual sinking or settling of the Earth's surface. This phenomenon can occur due to various factors, including the extraction of underground resources like water, oil, or minerals. When these resources are removed, the ground can lose support and begin to collapse, leading to depressions or sinkholes. Another cause of ground subsidence is the natural settling of soil over time, especially in areas with loose or saturated sediments. Additionally, changes in groundwater levels can contribute to this process. Understanding ground subsidence is important for urban planning and infrastructure development to prevent damage to buildings and roads.
